[QUOTE]I'm afraid it doesn't. FEC is just about how much light your flash decides to put out, it has nothing to do with what it's capable of. The problem with HSS is that the maximum power of your flash is actually decreased: it has nothing to do with how it's metering the flash./QUOTE]
I don't dispute that, all I know is the flash has more light in HSS when I up the FEC. Whether or not the light is metered up or actually producing more light isn't really that important to me (kinda like ISO) as long as it allows me to use a higher shutter on sunny days and a large aperture when I want, I am a happy camper. I own PW's as well but prefer the RP's for how I shoot.
